Arweave NFT Metadata Uploaded

This package can be used to create metadata files on the Arweave network. It first uploads NFT image and then creates a metadata JSON file for this NFT using this image and default fields from file uploader.js. It is created with an idea to be used with Solana blockchain and uses Metaplex NFT Standard but it isn't bound to Solana in any case and can be used with any other blockchain as well.

⚠️ Important note

I've disabled line which generates new AR wallet for the script use. From my understanding, newly generated wallets have 0 balance and shouldn't be able to approve TX on Arweave. Despite of it the script works well 🤷🏻‍♂️. So, to avoid any possible issues I've disabled it. Consider to use local Arweave wallet instead or this tool instead: solana-nft-uploader by @moshthepitt.

Use

Prerequisites:

• all images need to be in PNG format
• all images need to be placed in public/images/ folder
• CSV data need to be placed in public/data.csv

Then run:

node ./uploader.js

# or

node run upload

The result json file will be saved to ./public/arweave-images.json. This files consists of arrays of NFT objects with name / uri fields

TODO: More

There is React app to manually validate items. But it needs to be updated for better use.
